To (til whom it may col/merit:

Be it known that l, FRANCOIS hlorrrnnnn, a citizen of the Republic of France, residing at Lyon, France, have invented certain new Forming Tubes for lllectrode-llates; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pcrtains to make and use the same.

This invention relates to new and useful im rovcments in apparatus designed espocia ly for manufacturing electrode-plates adapted for use in storage batteries, the object being to provide a machine which willform tubular members of lead or of soft metal, which tubular members are provided with laterally longitudinally extending lugs, which are preferably Y-shapcd in cross-section, which lugs extend laterally from the tubes formed in the present machine and lon gitudinally thereof.

The invention consists in the combination and arrangement of parts which are shown in the accompan ing drawings, all as hereinafter more ful y described, and particularly pointed out in the claims, it bein understood that said drawings illustrate t 1e preferred construction, which may be departed from in the form, proportion, and minor details of parts therein shown, within the scope of the ta es of the invention.

' %n the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the views, Figure l is a longitudinal vertical sectional view taken approximately centrally through the machine above the supportin -standard thereof, op-

roximately on the p ane of line 1 1 of Fig. 5.

ig. 2 is a central longitudinal fragmentary sectional view of the lower portion of the o paratus illustrated in Fig. 1, approximately on the plane of line 1 1 0 Fig. 5. Fig. 3 is a top plan view of the formin -die which is used with this apparatus. ig. 4 is a detached fra mentary and enlar ed detail view showing t e manner in whic the plunger hereinafter referred to is connected with the head portion thereof. Fig. 5 is a fragmentary transverse sectional view, approximately in which the s eeve herein referred to is guided by the upper plates of the apparatus.

Fig. 6 is a fragmentary perspective view showing a portion of a sheet from which the electrodes are to be formed, and Fig. 7 is a partial elevational and partly sectional view of one of the electrodes which it'is intended shall be formed.

Referring to the parts, 1 1 are supports which rise from a suitable base or floor, which supports are adapted to hold the apparatus forming the subject-matter of this invention in an elevated position, and it is to be understood that the operative mechanism hereinafter particularly described is to be supported at such position above the floor that the tubes or c linders 2, which are formed thereby, may e forced downwardly durin the process of formation by the machine, an the elevation of the machine is preferably sufficient to permit the operator thereof passing below the forming-die hereinafter referred to while standing in an erect position.

Resting upon the standards 1 is a plate 3, having laterally-projecting flanges or lugs 4, which serve as supportinggneans cooperating with said standards. eyed to the plate 3 are a sufficient number of powerful posts 5, which are held connected with the plate 3 by means of wedges 6, projecting through said plate and through the posts or columns 5.

Mounted upon the columns 5 at a convenient distance above the plate 3 and connected with said columns in a similar manner is a plate 7. Connected with the columns 5 and at a predetermined distancebelow the plate 3 is a thicker plate 8, which is provided with a central orifice 9 therethrough, which orifice serves as a receptacle into which may be poured a sufficient supply of molten lead or other metal for the required purpose.

Spanning the distance between the plates 3 and 8 are hollow posts or columns 10, which are provided with flanges 11 abutting against the plates 3 and 8 to hold the said plates at a predetermined distance apart, and wedges 6 serve to lock the plate 8 upon the columns 5, before referred to.

Connected with the plate 8 and below the same is a recessed plate 12, which is provided with a central cavity 13, in which is held the forming-die 14", which is illustrated in plan in Fig. 3, set-screws 15 with angular heads passing through the member 12 and bearing against the die 14", so that said die may be adjusted to any required position centrally within the cavity 13 by means of said adjusting-screws. Below the'cavity'13 the plate 12 is provided with a perforation 16, which merges with the cavity 13 and completes the assage through the plate 12, but as theorigee 16 is of less diameter than the cavity 13, shoulders 17 are formed, upon which the forming-die rests.-

To secure the plate 12 to the plate 8,-bolts '18 with enlarged heads at the upper ends thereof extend through coincident perforations in the plates 8- and 12, while nuts 19 upon said bolts serve to hold the late 12 in close contact with the late 8, t ere being a sufficient number of the bolts 18 to I ho d the plate 12 rigidly in position to su port the forming-die 14 in close contact wit the lower face of the plate 8.

Restin above the plate 3,and traveling upon the 'ction-reducing ball-bearings 20 is a nut 21, which nut is provided with an internal and an external screw-thread. The nut 21 is approximately the thickness of thedistance between the'plates 3 and 7, and be tween the said nut 21 and said plate 7 there are provided cone-shaped rollers 23, which travel in channels or ways 24, formed, respectively, in the upper face of said nut 21 and the lower face of the plate 7.

Engagin the nut 21 and adapted to be driven by t einternal screw-thread 25 thereof is a sleeve 26, (shown in section in Fig. 5,) said sleeve being provided with a relatively small assage 27, which extends entirely throng said sleeve and in which rests the stem 28, which stem 28 is supported from the cross bar or head 29, as shown in Fig. 1,.

being locked to said head by means of the nuts 30, disposed relatively above and below said head. The head 29 is supported above the plate 7 upon hollow columns 31, which rest upon the I plate 7 and is locked to said plate bymeans of the bolts 32,which are set into screw-threaded orifices in the plate 7 and are held by the nuts 33',wh;ioh rest upon the upper face ofthe head 29, thereby supporting said head 29 in afixed position at a predetermined distance above the: plate 7 and supporting the stem 28. r

The sleeve 26 is provided at relatively dia metrically opposite sides with channels 35, which extend, preferably, theentire length of said sleeve, and to lock the sleeve against rotation keys 36 are inserted in said channels, said keysresting in similar channels in the sleeve and in plates 3 and 7, so that the sleeve is slidable vertically of the a paratus, as shown in the drawings,'but is eld against rotation.

Connected with the lower end of the sleeve 26 is a hollow plunger 38, through his 39 of which bolts\ 40 are projected, whic bolts enter screw-threaded orifices in the lower portion of said sleeve and secure the plunger 38 in position upon the lower end thereof. 6'5At the upper end of the plunger 38 ventorifices 41 are rovided, which lead from the exterior to t e longitudinal passage I 42 through said plunger 38.

Secured to the plunger 38, as shown in Fi 4, is a head ortion 43, there being coinci ent keyhole-s aged recesses formed in the lglunger and said ead, into which lockingeys 44, having enlargements upon opposite" ends thereof, are .inserted for the p' pose of .locking the head 43 to the pl er 38.

- As will be noted in Fig. 2, t e passage 42 through the plunger 38 is enlarged at the lower end of said plun er, and the head 43 is provided with a centre cavity 45, which is of substantially the diameter of the enlargement of said passage 42,-but the head 43 is provided also with an extension of the chamber 45, which is of lws diameter than said chamber, whereby an annular shoulder 46 is formed, which serves as a support for thelower member 47 of the compound packingring which is provided within the cavities oi" the plunger and head. The member 47 of this packing-rin is of greater diameter near its inner end, an has an attenuated collar 48, which projectsffor a short distance below the head 43, as shown in Figs.' 2 and 4. Within the enlarged cavity of the plunger 38 referred to there is another packing-'collar 49, which is held in a relatively fixed position in the plunger 38, and between these packingcollars-there is placed a packing 50, preferably of asbestos, which packing is designed to prevent the passage of molten metal through the passage 42, before referred to; I00

but owing to the. act that in spite of the ackin 50 the molten metal will be forced eyonfs'aid packing and upwardly through I the passage 42 the vent-openings 41 are pro i vided through the upper ortion of the lun- 1o 5 ger 38, so that such meta may be readily removed after it has found its way through the plunger.38.

The lower end of the stem 28 is perforated and screw-threaded longitudinally, as shown 1 m in Fig. 2, and in this screw-threaded erforation there is secured the attenuate screwthreaded upper end 52 of the lower extension 28 of said stem.-.

Resting upon the lower stem 28 and sup orted between the ortions 28 and 28 is t e inner portion 14"0 the formin -'die '14, (shown in a relatively exaggerate scale in Fig. 3,) the die14 comprising the parts 14 and 14 of which the 14 is held between the stem portions- 28 and 28*, be locked in a fixed position therebetween, i hile the outer portion 14 of this die is supported upon the annular shoulder 17 of the plate 12. This die is of peculiar con- 12 5 struction and the outer portion 14 is cut, away, as shown in the sectional view, Fig. 1, to provide the cavity 55. The u er faces of the sections 14 and 14 of the 'e are pro- Vided with channels, in which are heldrz'zdi 1&3

portion of the v 11111 er part I20 ally-extending ribs 56, which ribs, as will be noted in Fi 3, are provided with beveled ad'acent en portions in alinement.

I the adjacent edges of said dies, and from this passage 57 there extend in opposite directions radially Y-shaped passages 58 and 59, said passages extending radially from the passage 57 for the entire length of said passage 57, except at one point, where the passage 57 is intersected bythe slitting-knife 59 which knife is provided with a beveled end projecting into said passage 57 and is adapted to serve as a convenient means for cuttin a channel into the tube 2, which is forme by the machine, so that a knife or other slitting-tool may be passed into the channel formedb the knife 59 to sever the tube longitudinal y thereof, so that it may be fiat ened to the form shown in Fig. 6, in

which the -Y-shaped lateral extensions 60 extend longitudinally of the plates 61, with which they are inte ally formed in the first instance butrafter t e tube has been slit and flattened to the form shown in Fig. 6 said plate is then bent so that the Y-shaped extensions 60, instead ofextending longitudinally of the plate 61, will extend transversely thereof or circumferentially of the tube 62,

(illustrated in Fig. 7,) after which metal or filler may be inserted in the pockets 63, which are disposed circumferentiall-y both within the tube62 and exterior thereof.

The nut 21 is provided with the exterior screw-thread, as shown in-Fig. '1, -cxtcnd' and the plunger ,38 in a dil ection toward the j hand in the presence of two witnesses.

ing-circumferentially thereof, so as to adapt it to engage Withand be actuated by'a suitable worm or other driving means.

The operation of the machine is as follows: Molten metal being poured into the metal-- receptacle while the plunger is in an elevated position and the forming-die 14 properlycentered with relation to the stem 28 the nut 21 is rotated by any suitable means, (not. shown,) so as to project the sleeve 26 plate 8, thereby forcing the. lunger 38'into. the fluid metal therem an forcing such wpose disposed between the through the passage 57, thereby forming the tube 2, (shown in Fig. 1,) which tube is cut to predetermined lengths and manipulated, ashereinbefore indicated. When the plun ger 38 is forcing the metal between the diesections, there will bean upward pressure between the plunger and the stem 28, which upwarC ressure will force the slidable packing-collar against the packing 50, thereby compressing said packing to a suitable extent and retarding to a great degree the passage of the fluid metal between the plunger 38 and the stem 28; but to provide for the removal of any metal which may pass this packing the vent-orifice 21 is provided for the removal of any metal which finds its way past the packing.
